ERROR SparkContext: Error initializing SparkContext. java.net.BindException: Cannot assign requested address: Service 'sparkDriver' failed

There are a few different solutions

Get your hostname
```
$ hostname
```
then try to assign your host name
```
$ sudo hostname -s 127.0.0.1
```
Start spark-shell.
Add your hostname to your /etc/hosts file (if not present)
```
127.0.0.1      your_hostname
```

Add env variable

export SPARK_LOCAL_IP="127.0.0.1" 

load-spark-env.sh

Above steps solved my problem but you can also try to add
```
export SPARK_LOCAL_IP=127.0.0.1 
```
under the comment for local IP on template file spark-env.sh.template (/usr/local/Cellar/apache-spark/2.1.0/libexec/conf/)

and then
```
cp spark-env.sh.template spark-env.sh
spark-shell
```
If none of the above fixes, check your firewall and enable it, if not already enabled

Add SPARK_LOCAL_IP in load-spark-env.sh as

export SPARK_LOCAL_IP="127.0.0.1"

The load-spark-env.sh file is located in spark/bin directory

Or you can add your hostname in /etc/hosts file as

127.0.0.1   hostname

You can get your hostname by typing hostname in terminal

Hope this solves the issue!

Had similar issue in my IntelliJ

Reason : I was on cisco anyconnect VPN

Fix : disconnected from the VPN, this issue did not appear
